tit

An important object of the invention is to provide a machine of the above mentioned character, which is cpnvenient in use, and will expedite the manufacture of tires or tire-casings.

Other objects and advantages of the inwention will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a plan view of a machine embodying our invention, without. the tire in place thereon, Fig. 2 is a transverse sectional view taken on line2-2of Fig. 1, withthe tire in place, Fig. 3 is a similar view taken on line 3-3 of Fig. 1, Fig. 4c is a similar view taken on line t-1 of Fig. 1,-and, Fig. 5 is side elevationfpartly insection, of the cement applying means.

In the drawings, whereinfor the purpose of illustration, is shown a preferred embodiment of our invention, the numeral designates a table top, carried by legs or the like? (not shown). I

Rigidly mounted upon this table top 10 are pairs of vertical brackets of bearings 11, preferably four in number, and equi-distantly spaced, as shown. .lournaled in the brackets or bearings 11 are horizontal rotatable shafts 12, having their inner ends connected with grooved pulleys 13, or the like, driven from belts (not shown) extending from beneath the table top and passing through the opening 14:, as shown. Any other suitable means may be employed to ro tate the shafts 12, it being sufficient that all of the shafts are rotated at the same speed and in the same direction. Rigidly mounted upon the horizontal rotatable shafts 12 are grooved or coneaved wheels or pulleys 15 which are radially disposed and adapted to Specification of Letters Patent.

receive a tire or tire-casing 16 thereon, to rotate the same.

Disposed outwardly of and adjacent the grooved Wheels or pulleys 15 are vertical posts 17, rigidly mounted upon the table top 10, as shown. Pivotally connected to the upper ends 18, are normally inclined vertically swinging levers 19, having normally horizontally arranged brackets 20, rigidly secured thereto and preferably formed integral therewith, as shown. The brackets 20 are approximately inverted U-shaped and have horizontal shafts or spindles 21 journaled therethrough, carrying upper radially disposed grooved wheels or pulleys 22, corresponding in number and arrangement to the pulleys or wheels 15, as shown. The func tion of the upper wheels or pulleys 22 is to aid in guiding the tire or tire-casing 16 during its travel and to force the same into proper frictional engagement with the lower wheels or pulleys15. Connected with the outer lower ends of the levers 19 are re- .tractile coil springs 23, the lower ends of which are attached to thetable top 10, as shown. it is thus seen that when the levers 19 arereleased, the springs 23 will automatically swing the levers and the brackets 20 carried thereby to a substai'rtially vertical position, thus enabling the tire or tire'cusing 16 to be removed or inserted in place by an upward movement. Means are provided to swing the brackets 20 and wheels or pulleys 22, inwardly and downwardly in opposition to the springs 23, comprising flexible elements or cables 21-, attached to the levers 19, as shown at 25. These cables, as more clearly shown in Fig. 1, are connected in pairs, as shown at 26, with cables 27, passed about pulleys 28 secured to the table top 10. The cables 27 are connected with an operating cable 29, having connection with one arm of a bell-crank lever 30, as shown at 31 (see Fig. 3). a fixed bracket, as shown at 32, any suitable means (not shown) being employed to hold this lever in the upper or closed position. From the foregoing description, it is obvious that by swinging the lever BOupward-ly, the cables 21 will be pulledwhich will swing the brackets 20 downwardly, moving the grooved wheels or pulleys 22 into proper clampingor frictional engagement with the tire 'or tire-casing.

Means-are provided to pass or fold the of the posts 17, as shown at The lever 30 is pivoted to flaps or layers of the tire shoe into the same comprising a bracket or table 32, which may be rigidly attached to the table top 10, preferably in the position shown. Mounted to V intothe Whichare connected-a. depressing roller 37, disposed-above and in engagement with the .tool 34, as shownfiflit is obvioust at upon the upward novement of the tool arm 34, the same by engaging'the roller 37 will'be depressed, whereby .the head will be capable of moving the flapsor strips into engagement with the interior of the tire or 0 lever 40 is a toothed quadrant 42, adapted to e-shoe; -Pivotally connected with the g e 83, as shown at is a link or piterr-4O, which is pivoted to the tabletop as shown at 41. Arranged'adjacent the be engaged'by apawlflil, pivoted to the lever 40; as Show It is thus seen that means re provide to lock the tool arm 3% in ads ustment at the outer position.

Means are provided to roll and press the flaps or layers tothe inner stirface of the tire or tire-shoe, after they have been inserted therein, the same comprising a post or support 4L4, rigidly attached to the table top 10, preferably at the points shown. The upper end of the post 4:4 is preferably forked to receive a vertically swinging bearing 45, having pivotal connection therewith. J ournaled within this bearing is a rotatable vertically swinging shaft 46, but this shaft cannot partake of perceptible longitudinal movement with respect to the bearing 45. Rigidly attached to the inner end of the bearing 45 a grooved pulley -17, for receiving a belt (not shown) passing from be neath the table top through an opening 48,

'to drive the same. Any other suitable means may be employed to rotate the shaft 46. Rigidly connected with the outer end of the shaft lti is a tapered 0r conical roll it), adapted to enter the tire. or tire-shoe, and engage with the lower portion thereof, supported by the lower wheels or pulleys 15. Connected with the shaft 46, by means of a ring 50 having 'swiveled engagement therewith, is a compressible coil spring 51, serving to automatically shift the shaft 46 upwardly when released. The shaft 46 is moved downwardly, whereby the roll 49 is brought to the proper frictional engagement withthe tire ortire-shoe, by a cable or flexible element 52, connected with the shaft '46 by a ring 53, having swiveled engagement pivoted to a vertically swingingpivoted to a liXed bracket, as shown at 55.

By swinging the lever 5st upwardly, it is obvious that the tapered roll -19 may be moved downwardly into proper frictional. engagement with the tile or tire-shoe. Any suitable means may be employed to lock the lever 51- in the upper or closed position, if desired.

Means are provided to supply a liquid cc: ment or the like to the inner portion of the tire or tire-casing or the inwardly folded flap or layer thereof, comprising a prefer ably vertically arranged cylinder or shell 55, rigidly mounted upon the table top 10, prof erably in the position shown. The liquid cement or the like within this cylinder 55 is maintained at a. suitable pressure to feed the same, by a plunger-'56, having connection with a rod 57,. extending exteriorly of and above'the cylinder The rod 57 carries a head 58, by means of which the plunger 56 may be conveniently depressed. (.onnected' with the lower. outlet end of the cylinder 55 is a. pipe 59, preferably extending below and under the tire or tire-casing and has connection with a suitable spray -nozzle (30,

adapted to be passed within the tire or tireshoe, to supply theliquid cementto the desired parts. Connected in the pipe 59 is a suitable cut-oft valve 61 to control the charge of the cement.

Means are provided to blow air upon the parts of the tire or tire-casing previously treated with the liquid cement, to expedite the hardening of the cement. comprising a perforated pipe 63, arranged inwardly of and in proximity to the tire or tire-casing, as shown. This-pipe (53 has connection with -a pipe til, preferably extending through the table top 10, for connection with a suitable source of comprcssed-air (not shown).

lheoperation of the apparatus is as follows: To place the tire or lire-casing upon the grooved wheels or pulleys 15, the lever 30 is swung downwardly, whereby the springs will swing the brackets 20 upwardly, carrying the wheels or pullcys,22 upwardly, providing space whereby the tire may be arranged upon the wheels or pulleys 15. This having been done, the lever 30 is swung upwardly, whereby the upper wheels or pulleys 22 are brought into proper pivotal engagement with the tire or tire-casing. The tire or tire-casing will now berotatcd in one direction, preferably clock-wise. During this rotation, the flaps or layers carried by the tire or tire-casing. adjacent the tire-casing.

brought into action by swinging the lever 5i upwardly, which causes the roller *9 to be swung downwardly, whereby the folding of these flaps or layers is completed. By proper manipulation of the valve (52, the liquid cement may be applied to the folded flaps or layers, subsequently to which they are again subjected to the action of the roller l9. To aid in expediting the hardening of the cement, the same may be subjected to a current of air discharging perforated pipe It is to be understood invention herewith shown and described is to be taken as a preferred example of the same and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
